The Jahn-Teller effect in X& radical cations (X = Si, Ge, Sn) has been studied by ab initio CI calculations, using pseudopotentials. These cations undergo important distortions to Czv and C sv symmetries, from both structural and energetic points of view. Czv and Csv structures lie very close in en
The O-ccntcr in CaFa is invcstisatcd by performing multiple scattcrirq Xa calculations on the (Ore)'-cluster. In agreement with cxpcrimcnt, a strong Jahn-Teller distortion of tctrqondl symmetry is prcdictcd. Finally the ground state electronic structure of the cluster is discussed.
